## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability tenjin-crypto-context-weekly-open-rails-hard-filters-6da63b76
```

Example prompt: Pull up the Tenjin crypto-context weekly article titled 'Open Rails Hard Filters' from the crypto-context handle — I want to read their take on Bitcoin ETF flows, ether funds, and the CLARITY enforcement themes this week.

## When to prefer this

Choose this endpoint when you need to read a specific, already-published Tenjin crypto-context weekly article by its known slug, particularly for the 'open-rails-hard-filters' edition covering BTC ETF flows, Ethereum, and regulatory themes. Prefer this over generic web scraping when you want structured, paywalled crypto analysis content delivered via x402 micropayment. Use the wallet-address form of the handle for durable access.

## Known failure modes

- Article not found if slug is misspelled or does not exist (404)
- Payment not processed correctly via x402, resulting in 402 Payment Required response
- Handle not recognized or unclaimed creator with no wallet address fallback
- Rate limiting or access denial if payment header is malformed
- Empty or stale content if article has been unpublished or moved

## How this service works

Bitcoin ETF flows repaired only weakly while ether funds took the cleaner relative bid, and the stronger theme was control: CLARITY enforcement, permissioned tokenization, BitMart withdrawals, and event-contract review.

## Output

Returns the full text and structured content of the Tenjin weekly crypto-context article, including analysis of Bitcoin ETF flows, Ethereum fund performance, CLARITY regulatory enforcement, permissioned tokenization developments, BitMart withdrawal events, and event-contract reviews, formatted as an HTTP response object with article body and metadata.
